EDWARD CHESHIRE, OF ST. PETERSBURG, FLORIDA 'VISE Application filed July25, 1927. Serial No. 208,077.

The invention pertains to a vise and more v particularly to an articleadapted to secure material in position so that the article or holdingunit may be used to guide said material into operating position invarious machines or devices.

It is an object of this invention to provide a portable device of suchcharacter as will hold .material in xed position with reference to saiddevice.

Another object is to provide a device for holding material, the securingmeans being of such character as cannot be accidentally loosened.

A further object is to provide a. device which is inexpensive to malreand maintain, and is portable and readily adapted to secure material fortype-high or other operations where such material is to be aleeted bymachine operations.

A still :further object is to provide a holding means in the form of atable member having adjustable securing means for the ready adaptationto material of any size, shape er character.

Other further and more specilic objects will readily occur from thedetailed description, claims and drawings appended hereto.

In the drawings, wherein like reference characters are used to designatelike parts- Figure 1 is a side elevation, illustrating the holdingdevice as applied to a router, jig-saw and type-high machine;

Figure 2 is a plan of the assembled holding device;

Figure 3 is an enlarged broken sectional elevation of the holding devicetaken substantially on the plane as indicated by the line 3-3 of Figure2, the dottedlines being used to indicate material held in operatingposition;

Figure l is a fragmentary enlarged sectional elevation take-nsubstantially on the plane as indicated by the line 2 4; of ure 2; and

Figure 5 is a fragmentary enlarged sectional elevation takensubstantially on the plane as indicated by the line 5 5 of Figure 3.

In subjecting material to operation in a machine such as the router,ig-saw and typehigh machine 10, it often becomes necessary for thismaterial to be moved with respect to the operating tools, and it is forthis purpose that the holding device taking the form of a plate holderis employed. The router, Jig-saw and type-high machine 10 is providedwith a router table 1l, saw table 12, a motor and chuck 13, and ajig-saw 111, all selectively operated by means of mechanism set inmotion by the belt 15 from any convenient source, such as an electriclmotor, said parts being controlled from pedal controlled means 16, thedetails of this machine being more particularly described in co-pendingapplication Serial No. 196,196, filed June 3, 1927, Cheshire. i

The plate holder 1'?, preferably of metal and of a convenient size, isprovided with an end plate 18 secured thereto by suitable means, suchasthe screws 19, and said plate holder is provided with a longitudinallyeX- tending channel 20, preferably placed on the longitudinal centerline of saidplate holder and disposed normally with respect to the endplate. lt will be noticed that this channel 2O has channels 21 disposedbelow the plane of the top of the plate holder, such channels formingguideways for a vise jaw 22. yA rack 23 is secured in the' channel 20 bysuitable means such as the screws 24C, said raclr being Vdisposed whollybelow the channels 21. The rack is provided with teeth 25 which toetoward the end plate and have suitable locking and sloping portions, theangle therebetween being substantially 600.

The vise jaw 22-comprises a leg 26 provided at one end thereof withatransverse pin 27 adapted to have pivotal sliding motion with respect tothe channels 21, a portion of said leg 26 being provided with teeth 31corresponding in shape and adapted to cooperate with the teeth 25 buttoeing in an opposite direction. Said vise jawv is provided with anupstanding threaded leg 28extending substantially at right angles to theleg 26, being adapted to support and have threaded engagement with a setscrew 29, said set screw being adapted to wedge material 30 between thevise 22 and the end plate 18. The channels 20 and 2l are preferably openended, one of said ends being closed by the end plate 18, the otherbeing preferably open so that the vise jaw 22 may be readily applied orremoved.

It will be appreciated then that work 30 may be applied to the plateholder 17, one end of said work abutting the end plate 18. The vise jaw22 is slid in the channel toward the work 30 and teeth 3l are let intocontact with the teeth 25. Thefthumb screw 29listhe'n tightened so thatthe work 30 is wedged between the end plate 18 and the vise jaw 22, andit will be noted that due tvo-the shape of the teeth, the vise jawcannot slip away from the worlrthough-the teeth are so shaped that theymaybe moved over each other toward the work. It will also be noticedthat as the pin 27 isremoved from the end of the work abuttingportion'ofthe thumb screw 29 and preferably extends under 4a por-tion of the work,that there can be no relative :movement between the visefj aw and saidwork asfto remove the vise jaw there must be a rotation around the pin27. This, then, prevents any accidental freeing of the work due to thefact that the vise jaw cannot be .jarred from the rack 20, it beingfirst necessary to slacken the set screw to free the visejaw. It will beappreciated that the plate holder and the work may be manipulated as aunit'in any machine, such as the machine 10 illustrated, there thenbeingno danger of losing anyV ofthe work 30 especially When'said work ismade-'up of separate slugs, the whole unit being readily adapted to beremoved from one table to another table or from one machine to kanotherInachine for operation.

It is to be understood that I do not wish to be limited by the exactembodiment of the device shown as other and various forms of the devicewill readily occur to those skilled in the art.

'I claim Y l. A work holder, comprising, in combination, a supporthaving a channel formed therein, the side walls of said channel. beingrecessed to provide runways, a supporting pin adapted to slide in Asaidrunways, a work clamping device connected to the supporting pin andadapted to travel therewith lengthwise of the channel, and meansdisposedwithinthe channel for cooperatingwith the work clamp to preventaccidental rearward displacement thereof.

2. A vise comprising a baseplate provided in its upper face with kanopentop channel having grooves extending longitudinali in the side wallsofthe channel, an upstandino fixed jaw extending across the base Vplatetransversely ofthe channel and projecting at opposite sides thereof, amovable jaw having a base slidably mounted in the channel and providedwith an upstanding arm rising through the'open top of the channel, the

base of the movable jaw being provided with trunnions slidable in thegrooves and upon which the movable jaw may be swung vertically, thebottom of the channel having teeth, and the bottom of the base of themovable jaw having teeth for selective engagement with the teeth of thechannel.

3. 'A vise comprising a base. plate provided at its upper face with anopen top channel intersecting opposite edges of the base plate, the sidewalls of the-channel being provided with longitudinal grooves, anupstanding Vfixed j aw secured to one edge of the base plate andextending transversely across one end of the channel, a movable jawhaving a base slidably mounted in the channel and provided with anupstanding armriSing through the open top of the channel, thebase o'fthemovable jaw being provided withtrunnions slidable in the grooves andupon whichvthe movable jaw may be swung, said movable jaw beinginsertable and removable through lthe open end of the channel oppositethe `fixed jaw, the bottom of the channel having teeth, the bottom ofthe movable jaw havin-g teeth for selective-engagement with theteeth ofthe channel, and a set screwcarried by the upstanding arm of themovablejaw in substantial parallelism with the base plate.
